Axial C+ arterial phase

Atherosclerotic disease of the abdominal aorta, bilateral iliofemoral arteries and distal branches is demonstrated. There are fusiform aneurysms involving the right common femoral artery and proximal half of the right superficial femoral artery, right popliteal artery, and left popliteal artery extending to the tibioperoneal trunk. Mural thrombus formations are seen within the aneurysms.

Case Discussion

This case demonstrates peripheral arterial aneurysms (right femoral and bilateral popliteal artery aneurysms) in an elderly female. Popliteal artery aneurysms are the most common peripheral arterial aneurysms. Approximately 50% of popliteal artery aneurysms are bilateral and about 34% are associated with femoral artery aneurysms 2. Mural thrombus within a popliteal artery aneurysm results to an irregular angulated lumen with a characteristic "dog leg" appearance.
